+# init-letsencrypt.sh
+# Bootstrap Let's Encrypt certificates for dociva.io
+#
+# This script solves the chicken-and-egg problem:
+#   Nginx needs SSL certs to start on 443,
+#   but Certbot needs Nginx running on 80 to verify the domain.
+#
+# Solution: create a temporary self-signed cert → start Nginx →
+#           obtain the real cert → reload Nginx.
+#
+# Usage:  chmod +x scripts/init-letsencrypt.sh
+#         sudo ./scripts/init-letsencrypt.sh
